Do our images of one God in three persons reflect God well? Throughout history, Christians have pictured the relationships between Father, Son, and Holy Spirit through analogies. Such illustrations--some from the West but also from Latin America, Asia, Africa, and other places--come laden with theological ramifications that the church has rejected (heresies) or embraced (doctrines). In Three in One, William David Spencer shares a lifetime of insights from teaching within the global church, bringing fresh images and analogies of the Trinity to deepen our theological vocabulary. Drawing from his extensive teaching in geographically and culturally diverse contexts and his artist's passion for evocative words and visuals, Spencer offers readers a rich, multifaceted, and practical exploration of the Trinity. Alongside historical and contemporary theology and biblical studies, he considers the strengths and shortcomings of various analogies used to explain the Trinity, such as: LightWaterThe Celtic knotThe totem poleMusical harmoniesThe human bodyThe familyReaders of Three in One will gain a personal understanding of the Trinity as well as tools for teaching about the Trinity in adult and children's ministry contexts.
